How Big Ethanol Hopes You’re a Dope Biomass

Posted September 3, 2013 | folder icon Print this page

Growth Energy recently unveiled a national ad campaign to tell “the truth about ethanol” and the Renewable Fuel Standard (RFS)—the federal mandate that requires oil refiners to blend ethanol into gasoline. But the ethanol lobby has a curious definition of “truth,” as many of their claims are incomplete, misleading, or outright false.

NASCAR doesn’t use ethanol because it is a “high performance” fuel, but because it is “product placement”

Growth Energy proudly declares that NASCAR uses ethanol. This should not be a surprise, however, because Growth Energy and the National Corn Growers Association are official sponsors of NASCAR. As a NASCAR official confirmed to Delaware Online, ethanol’s relationship with NASCAR amounts to a “sports product placement agreement.”

When we see LeBron James wearing Nikes, Phil Mickelson swinging Callaway golf clubs, or people in the TV show The Office using Apple products, we should not be surprised because these are all paid product placement. The fact that NASCAR uses ethanol does not say much if anything about ethanol, other than the fact that NASCAR is paid to use it.

Ethanol increases ozone air pollution

When Growth Energy says that ethanol is “clean burning,” they fail to mention that burning ethanol increases air pollution, particularly ozone. As Scientific American explains:

Because burning ethanol can potentially add more smog-forming pollution to the atmosphere, however, it can also exacerbate the ill effects of such air pollution. According to [Stanford University environmental engineer Mark] Jacobson, burning ethanol adds 22 percent more hydrocarbons to the atmosphere than does burning gasoline and this would lead to a nearly two parts per billion increase in tropospheric ozone. This surface ozone, which has been linked to inflamed lungs, impaired immune systems and heart disease by prior research, would in turn lead to a 4 percent increase in the number of ground level ozone-related deaths, or roughly 200 extra deaths a year. “Due to its ozone effects, future E85 may be a greater overall public health risk than gasoline,” Jacobson writes in the study published in Environmental Science & Technology. “It can be concluded with confidence only that E85 is unlikely to improve air quality over future gasoline vehicles.”

More recent research has reached a similar conclusion that ethanol increases ozone pollution. The Union of Concerned Scientists, an environmental group, cautions, “If done wrong, the production of biomass for biofuels like ethanol could destroy habitats, worsen water or air quality, limit food production and even jeopardize the long-term viability of the biomass resource itself.” That does not sound “good for the environment.”

Growth Energy’s argument that ethanol has lower greenhouse gas emissions is also debatable. Lifecycle greenhouse gas emission studies are difficult and complicated to conduct. As a result, some say ethanol decreases greenhouse emissions, while others say that ethanol increases greenhouse gas emissions. A study published in Science that includes land use changes finds that corn-based ethanol nearly doubles greenhouse gas emissions over the next three decades and continues to increase emissions for the next 167 years. The Energy and Resources Group of the University of California, Berkeley finds that “if indirect emissions [resulting from the production of ethanol] are applied to the ethanol that is already in California’s gasoline, the carbon intensity of California’s gasoline increases by 3% to 33%.”

Lastly, it is disingenuous for Growth Energy to include the greenhouse gas emissions of cellulosic ethanol in its graphic because only miniscule amounts of cellulosic ethanol are produced. Currently, the U.S. consumes more than 133,000,000,000 gallons of motor gasoline a year. In contrast, in 2011, zero gallons of cellulosic ethanol were sold commercially; last year only 20,069 gallons of cellulosic ethanol were sold commercially; and so far this year only 129,731 gallons have been sold.

Ethanol has helped increase domestic fuel production, but not nearly as much as increases in domestic oil production

If ethanol improves the economy, as Growth Energy argues, then there is no reason for the Renewable Fuel Standard to exist. If that is Growth Energy’s argument, we agree. The problem with the Renewable Fuel Standard is that as a mandate, its purpose is to force people to use something they would not otherwise use, or to use it in higher quantities than otherwise. By forcing people to use more ethanol that they would otherwise use, the Renewable Fuel Standard harms the economy, because “the economy” is simply a way for us to trade with each other and improve our situations through cooperation. If someone forces vegetarians to buy hamburgers, or non-smokers to buy cigarettes, that might look like “economic growth” and “job creation” but it doesn’t actually make Americans better off. By the same token, if the government forces people to use ethanol, that’s not genuine prosperity.

Growth Energy’s chart showing declining net oil imports is accurate, but it fails to state the biggest reason for the reduction in oil imports—increasing domestic oil production, not ethanol. Net oil imports are falling because U.S. oil consumption is holding steady, domestic fuel production is increasing, and the U.S. is exporting a greater amount of petroleum products. U.S. liquid fuels production rose 39 percent from 2005 to 2012, according to data from the Energy Information Administration (EIA). Biofuels accounted for 32 percent of the increase, while petroleum contributed about 68 percent. Because of increased domestic production and fairly flat demand, the United States is exporting petroleum. U.S. petroleum exports almost tripled between 2005 and 2012. Growth Energy’s chart is based on net imports, which are gross imports minus exports. Increased domestic petroleum production, not ethanol production, is the biggest force behind America’s reduction in imports.

Earlier in the year, EIA projected that monthly domestic oil production was on track to surpass net imports for the first time since 1995. EIA attributes this change primarily to “rising domestic crude oil production, particularly from shale and other tight rock formations in North Dakota and Texas.” America is indeed weaning itself off of foreign oil, but the ethanol industry does not deserve nearly as much credit as they claim.

Oil companies oppose the Renewable Fuel Standard because it hurts their business, and ethanol companies support the Renewable Fuel Standard because it requires the American people to use their product

Growth Energy writes, “For every gallon of renewable fuels that is blended into gasoline, it’s one less gallon of gasoline the oil industry can sell…It’s really quite simple. It’s all about money.” Growth Energy knows this statement is incorrect. They are correct, this is about money—that’s not the issue. The issue is whether “for every gallon of renewable fuel that is blended into gasoline, it’s one less gallon the oil industry can sell.” This is inaccurate because a gallon of ethanol is not the same as a gallon of gasoline. A gallon of ethanol contains 33 percent less energy than a gallon of gasoline and therefore it takes more gallons of ethanol to travel the same distance as using gasoline.

The argument about money applies equally to the ethanol industry. Of course oil companies do not want to be forced to sell their competitors’ products, in the same way Honda would not want to be forced to sell a certain percentage of Chryslers. But this is exactly what the Renewable Fuel Standard does.

Growth Energy and ethanol companies support the Renewable Fuel Standard because it forces oil companies to sell ethanol. Growth Energy, Cargill, ADM and other major ethanol producers could start their own gas stations and sell as much ethanol as people would like to buy, but that is not what they want. By supporting the Renewable Fuel Standard, Growth Energy wants to force people to sell Growth Energy’s products.

Subsidies for some energy sources does not justify subsidies for ethanol

Graphic from Growth Energy:

This chart is misleading for several reasons. The most obvious is that the chart conveniently excludes most of the Obama administration, when subsidies for green energy technologies skyrocketed.  For example, according to the Energy Information Administration, between fiscal year 2007 and fiscal year 2010, subsidies for renewable energy almost tripled. In fiscal year 2010, biofuels received 3.5 times the subsidy level that petroleum liquids and natural gas received outside the electricity generation sector.

The chart correctly notes that the Volumetric Ethanol Excise Tax Credit (VEETC), which paid the ethanol industry to produce ethanol, expired at the end of 2011. According to the White House’s budget, in 2011, the VEETC was worth $6.5 billion and in 2012 it was worth $3.6 billion.[1] That’s nearly twice as much money as the oil and gas tax credits were worth over 91 years.

Another problem is the way oil subsidies are calculated. According to the report the chart is based upon, the only “subsidies” for oil and natural gas companies were “the expensing of intangible drilling costs and the excess of percentage over cost depletion allowance.”[2]  These tax deductions are akin to those that businesses receive for depreciation (percentage depletion allowance) and research and development (expensing of intangible drilling costs). All businesses receive the domestic manufacturing tax deduction, but the oil and gas industry can only claim a 6 percent deduction of its profits, while all other manufacturers can deduct 9 percent.  Large oil companies, however, are specifically excluded from some of the incentives that the small independent oil and gas companies receive, as IER explains in a recent analysis.

So-called subsidies for oil are much different than subsidies for ethanol. The VEETC, on the other hand, provided 45 cents for every gallon of ethanol blended with gasoline. Though the ethanol tax credit expired, the federal government continues to offer tax credits to biodiesel producers.

Lastly, ethanol has been used in internal combustion engines for nearly 190 years—ever since Samuel Morely experimented with ethanol mixed with turpentine. Ethanol is not a “new fuel” that needs subsidies to compete.

Ethanol damages engines, especially small engines

Graphic from Growth Energy:

Growth Energy tries to argue that higher ethanol blends won’t damage automobiles. This is false. EPA has only said that E15 is okay for cars model year 2001 and newer. Cars older than model year 2001 could be damaged, according to EPA’s waivers. But this assumes that EPA’s study of the impact of E15 is correct. A study by the Coordinating Research Council finds that 5 million cars could experience engine damage or failure from E15. As such, several automobile manufacturers will not warranty vehicles using E15.[3] Furthermore, AAA has called for a suspension of E15 sales, citing “consumer confusion and the potential for voided warranties and vehicle damage.”

But the problem with ethanol is not isolated to just automobiles. Ethanol poses even more problems for machines with small engines. As AAA explains, gasoline blended with even as little as 10 percent ethanol can accelerate engine failure in boats, motorcycles, lawnmowers, and other small engines. As a result, some boaters are turning to ethanol-free gasoline. A gas station owner in North Carolina, for example, says many customers are willing to travel across the county for gasoline that they know won’t harm their boats. The National Marine Manufacturers Association (NMMA), the trade group for the recreational boating industry, also opposes gasoline blended with more than 10 percent ethanol.

Forcing oil companies to blend greater and greater amounts of ethanol increases gas prices

While it is true that on a per gallon basis, ethanol is less expensive than pure gasoline, that is not the correct measure. The real unit of comparison is not the cost per gallon, but the cost per unit of energy. Because ethanol contains about 33 percent less energy than gasoline, as ethanol content increases, fuel economy decreases. AAA’s Daily Fuel Gauge Report reflects this scientific fact; the BTU-adjusted price of E85, ethanol that contains up to 85 percent ethanol, is consistently higher than conventional gasoline. A year ago, regular gasoline cost about 70 cents less than E85 on a miles-per-gallon basis. Even with a record corn harvest driving down corn prices this year, E85 still costs about 20 cents more than conventional gasoline.

As for the study Growth Energy references, the Iowa State study claiming that ethanol production has suppressed the growth in gasoline prices is very misleading. It takes for granted the current refinery capacity and other infrastructure that industry uses to deliver gasoline to motorists, without realizing that federal policies over the years have distorted the development of these markets. Ethanol only survives in the market place at its current levels because it is propped up by artificial mandates and preferential tax treatment.

The regression analysis of the Iowa study doesn’t accurately capture the timeline that would have occurred had the free market been allowed to operate. Of course, a sudden disappearance of all ethanol would cause a bigger price spike in the Midwest than in the East Coast. That’s because the artificial federal support has displaced the development of oil-based gasoline delivery in the Midwest more than in other regions. The fact remains that ethanol (at its current market share) is very inefficient. Taxpayers and consumers would be richer if the government dropped its support programs for it. For a more complete explanation, see this analysis.

Even if the Wisconsin and Iowa State study is correct that ethanol decreased gasoline prices in 2011, blending increasing amounts of ethanol threatens to increase, not decrease, gas prices in the near future.  A recent study by the Energy Policy Research Foundation, Inc (EPRINC) finds that E10 prices could spike as much as 50 cents to $1.00 per gallon in 2014. EPRINC attributes the increase to “constraints in cost effective opportunities to blend larger volumes of renewable fuels into the U.S. gasoline pool,” otherwise known as the blend wall. When the blend wall is hit, refiners must purchase Renewable Identification Number (RIN) credits, which allows them to not meet their required biofuel quotas. The value of RINs has skyrocketed by 2300 percent during the past year due to the approaching blend wall. The cost of the RINs is passed onto the distributor and then to the customer. Another study by NERA Economic Consulting finds that by 2015 the federal ethanol mandate could raise diesel costs by 300 percent, gasoline prices by 30 percent, and reduce take-home pay for American workers by $580 billion.

As we get closer to the blend wall, the impact of the Renewable Fuel Standard will become more and more severe.

The ethanol industry no longer receives direct subsidies; instead they have something better—a mandate that Americans use their product

The ethanol tax credit may have expired, but the ethanol industry continues to enjoy what is arguably an even more attractive subsidy: the Renewable Fuel Standard (RFS). Passed in 2005 and expanded in 2007, the RFS requires oil refiners to blend increasing amounts of ethanol and other biofuels into the nation’s transportation fuel supply, with the goal of blending 36 billion gallons by 2022.

As Kevin Drum of Mother Jones observed soon after the ethanol tax credit expired, ethanol subsidies are “not gone, just hidden a little better.” The Congressional Budget Office (CBO) noted in 2010 that the ever-rising federal mandate would obviate the need for a tax credit: “In the future, the scheduled increase in mandated volumes would require biofuels to be produced in amounts that are probably beyond what the market would produce even if the effects of the tax credits were included.” As Drum explains, “Demand for ethanol is driven by the mandates, not by the tax credit.”

By forcing refiners to purchase ethanol regardless of whether it makes economic sense, the RFS creates artificial demand for ethanol. Tax credits, on the other hand, make production more profitable, but don’t compel people to purchase the products produced. In other words, the RFS gives ethanol producers a much more valuable gift than tax credits—it gives them repeat customers.

Further, the U.S. oil and gas industry does not receive the federal subsidies that Growth Energy cites in the above graphic. The International Energy Agency (IEA) annually estimates global fossil-fuel consumption subsidies that measure what developing countries spend to provide below market cost fuel to their citizens. The IEA is a creation of the Organization for Economic Cooperation and Development (OECD), which represents the developed nations of the world. In 2011, IEA found fossil fuel consumption subsidies total $523 billion, 27 percent higher than the 2010 total of $412 billion. This increase is almost entirely due to the increase in international energy prices, particularly oil prices. Oil subsidies make up over half of the total fossil fuel consumption subsidies, while electricity makes up 25 percent, natural gas 20 percent and coal less than 1 percent.

Developing countries artificially lower energy prices to their citizens, paying the difference from their government resources. Such welfare transfers are akin to the U.S.’s Low Income Home Energy Assistance Program (LIHEAP), and are different from subsidies in the name of commercializing uneconomic energy sources such as on-grid wind or solar. The United States and other developed countries offer support to energy production in the form of tax credits, loan guarantees or use mandates, which are not included in IEA’s fossil fuel consumption subsidy calculations since they are directed towards production rather than consumption of the fuel.

Conclusion

Millions of gallons of ethanol would be produced and used every year without the Renewable Fuel Standard since refiners would use it as an oxygenate. The problem is not ethanol per se, the problem is the Renewable Fuel Standard, which artificially increases the amount of ethanol required. The Renewable Fuel Standard increases gas and food prices, decreases fuel economy, and damages small engines. As such, it is time for Congress to repeal the mandate.

    Yes, Corn Ethanol seems like a bad idea in several ways. It competes with corn as a food source. Next, I believe it’s true that Ethanol is a net energy sink (not a source).

    But my understanding is that the reason we use it in gasoline blends is as an octane booster substitute for MBTE, which has caused serious problems with water contamination.

    So there is no easy answer here. I would say that if the “free market” and the gas industry wants to use MBTE, and has no substitute, then this is one good example for regulations and a subsidy to force the market to do the right thing.

  • 2maxpower

    you missed the biggest argument against ethanol (from corn). the cost of production is more then one gallon of diesel to gallon of ethanol. that alone should be the reason for not subsidising.

    if cleaning the CO2 from the atmosphere is the goal then burning fuel to produce inferior fuel is stupid.

    which brings us to the real reason for the global warming fraud. it is about power / control /and redistribution of wealth (read stealing from producers)

  • 2maxpower

    it is NOT an octane booster. high octane fuel at the pump has the least or no ethanol.

    new engines are designed to run without MBET. ethanol came much later. engines were redesigned before ethanol was introduced to the market. it is pure bullsh!t play. something governments are good at.

    Those reading this should be aware that the IER is an agenda driven organization with financial support from conservatives and climate deniers such as the Koch brothers and with ties to the CATO institute. Growth Energy’s positions commented on here are easily explained and rebutted.

    Argument #1 – ‘high performance’ or ‘product placement’. Both positions can be true as just because something has a‘ product placement’ relationship does not make their claims false. Almost all automotive engineers recognize what the advantages of ethanol as a fuel are. It is the highest octane fuel available today. There is no way to deny that scientific
    fact. It also results in better performance because it reduces post ignition knock under higher loads. This is associated with its higher latent heat of evaporation.

    Argument #2 – Ethanol increases ozone air pollution. This has been an area of significant
    misinformation and can even be found in information from the EPA. Ethanol is not blended with an E0 gasoline to which comparisons are made, but with a ‘blend stock’ made
    specifically for ethanol blending. To simplify the explanation, it is the blend stock that contains the ‘smog-forming ‘ pollutants, not the ethanol. These fuel standards were written with significant petroleum industry input to their advantage to allow them to dispose of high polluting components of the refined barrel of crude oil. In a similar manner, GHG comparisons are skewed to petroleum. The standard for gas is from 2005, before tar sands and fracking ‘increased our reserves’. Trend lines are clear, biofuels are getting better and petroleum fuels are getting worse. Changing these GHG calculations in the RFS to reflect today’s realities might be an appropriate updating of the regulations

    Argument #3 Ethanol production is not nearly as significant as domestic oil
    production. There are economic studies that show the government subsidies to the oil and gas industry are essential to the development of these new fracked and heavy oil resources. Ethanol production receives No subsidies. The argument presented that the ethanol mandates are a form of subsidy fails to recognize that there is presently a
    mandate to use 90% gasoline. If the ‘free market’ were to prevail, we would still have lead in our gasoline. Petroleum products carry heavy health and environmental hazards with them and maybe ethanol also does to a considerable lesser degree. Government regulation of our communally held resources of air and water are appropriate. Forcing people to
    use gasoline or fossil fuels is not prosperity and has significant downsides for associated liabilities not within the economic pricing system.

    Ethanol damages engines. There is no proof that higher blends of ethanol damages
    vehicle engines. The EPA has not declared E15 ‘safe’ for older vehicles, but this is different than saying it damages vehicles. The EPA has decided to be highly conservative.
    Indeed the study sponsored by the oil industry that the AAA has quoted shows that , among the vehicles tested, 80% remained within the manufacturers engine specifications even when run on E20. The remaining vehicles also failed on E0 and was probably associated with a manufacturers recall.

    Argument #4 Blending greater amounts of ethanol increases gas prices. It is true that
    ethanol does not have as many BTU’s per gallon as gasoline, but energy is also not the correct measure. First, adding any oxygenate to fuel as required to improve air quality will lower energy density. E10 actually has a slightly higher energy density that gasoline with MTBE. But more importantly, the potential energy efficiency of the fuel means more miles per BTU. At mid-level blends of E25 or more, ethanol blended fuel can give more MPG than gasoline. That is the future the RFS should be leading us to.

    Argument #5 – The RFS represents a mandate for ethanol use,
    which is better than a subsidy. The ugly truth here is that the RFS does NOT mandate the use of ethanol, only the use of a renewable fuel. This can be biodiesel, bio-butanol or petroleum like drop-ins. The RFS is flexible and allows adjustments and carryovers from year to year to meet overall goals. The renewable fuel industry can meet the required renewable fuel goals, although they may not be met with ethanol alone.

    Moving toward increased ethanol blending would be beneficial for future CAFÉ and efficiency standards, especially if these standards were updated to be based on BTU’s used rather than gallons used. All beneficial regulations can be difficult, but they need to be based on facts, not propaganda.

  • B_Brandon

    Again, you are woeflully under-informed. Ethanol IS the highest octane fuel available and is sought as a octane booster as well as a oxygenant. High octane fuel at the pump often does not contain ehtanol because of low volume marketing issues.

  • B_Brandon

    You are woefully under-informed. USDA figures is one BTU in results in 2.2 out. Only about 10% of this inlput is diesel.

  • 2maxpower

    woeful me.

    alcohol isn’t “octane booster”. FULL STOP. octane is measure of ignitability of fuel and has no bearing on performance in itself. incorrect octane for a specific engine can effect performance only if it (the fuel) ignites out of sequence. i.e. not by means of the spark plug.

    alcohol DOES have a faster flame front. this is why high performance cars like Nascar and drag cars use alcohol based fuels.

    don’t conflate octane with burn rate. they are different

    Ethanol is not in the highest octane fuels at the pump because in street vehicle it (ethanol) degrades performance.

    Ethanol does not have an octane rating. Octane is measure of gasoline’s ignitability.

  • 2maxpower

    I don’t think you are using accurate numbers. USDA …why that is like quoting the United Nations as a source.

    you are swallowing a lot of socialist propaganda.

    if those numbers were honest ethanol would not need to subsidised.

    …are you a troll ?

  • randydutton

    The higher the ethanol content, the more sales tax motorists have to pay to travel the same distance. The states have a vested interest in dropping gas mileage so they can collect more revenue.

    Same for damaging or destroying vehicles and open-cycle engines. Replacement and repair means more sales tax for the state.

    It’s the ‘broken window’ theory of economic growth. There is one bright spot…I worked the topic into my novel, The Carbon Trap: (Carbon Series – Book 1)

  • randydutton

    B_Brandon: First, visit http://www.historicvehicle.org/Resources/Resources/Ethanol to see how damaging ethanol (even E10) is to vehicles.

    When I ran for the WA state legislature in 2008, a state Dept of Ecology official told me that any more than 2% ethanol in the fuel and Seattle exceeds the EPA Ozone Attainment Levels. What really amazed me is how uninformed the incumbents were in biofuel science and economics. And my opponent was the Leg. Majority Leader! They rely too heavily on lobbyists to tell them what to believe and typically their expertise is more in law and not science or economics.

    And as for you thinking those opposing ethanol have conflicting interests, I own 124 acres of timber which might someday be convertible to biofuel, and yet, I still oppose ethanol.
